Studies of diving beetles suggest sperm evolution may be driven by changes in female reproductive organs, challenging the paradigm of post-mating sexual selection being driven mostly by competition among sperm. In the process, the researchers discovered an unexpected and stunning variety of sperm form and behavior.
Several periods of field work during 2008 have led to the discovery of a new species of bamboo-feeding plant lice in Costa Rica's high-altitude region Cerro de la Muerte. The discovery was made thanks to molecular data analysis of mitochondrial DNA. The collected records have also increased the overall knowledge of plant lice (one of the most dangerous agricultural pests worldwide) from the region...
In a study published last week in Proceedings of the National Academy of Sciences, a team led by Dr. Vincent Poitout of the University of Montreal Hospital Research Centre has made an important step forward in understanding how insulin secretion is regulated in the body. This discovery has important implications for drugs currently in development to treat Type 2 diabetes, a disease which is...
In a new clinical practice guideline for drug treatment of type 2 diabetes, the American College of Physicians recommends metformin to treat type 2 diabetes based on a comparative effectiveness analysis of oral medications.
In 2004, concerns about antidepressant drugs increasing suicidal thoughts and behaviors in young patients prompted the FDA to issue a rare "black box warning." Now, a new analysis of clinical trial data finds that treatment with the antidepressant fluoxetine did not increase -- or decrease -- suicidality in children compared to placebo treatment.
A widely used universal behavioral prevention model in schools appears to be associated with lower rates of teacher-reported bullying and peer rejection, according to a report in the February issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.

In one year alone, over 4,500 children in the United States were hospitalized due to child abuse, and 300 of them died of their injuries, Yale School of Medicine researchers report in a new study. The findings are published in the March 2012 issue of Pediatrics published online Feb. 6.
Both subjective and objective cognitive impairment are highly common among non-demented elderly Swedes, with an overall prevalence of 39 percent and 25 percent respectively, according to a nationwide twin study by researchers at the Aging Research Center of Karolinska Institutet, Sweden. The study confirms higher education as a major protective factor and stresses the importance of environmental...
A Henry Ford Hospital study has found that using two types of common asthma medications in combination reduces severe asthma attacks.Researchers say using long-acting beta-agonists in fixed-dose combination with inhaled corticosteroid (ICS) appear to reduce asthma attacks as well as or better than corticosteroids alone. Patient groups who had in greatest benefits were patients 18 and older,...
A large Scandinavian study, that has been running for 30 years, has finally provided convincing evidence that the combined oral contraceptive pill does, indeed, alleviate the symptoms of painful menstrual periods reports scientists from the University of Gothenburg, Sweden.
Researchers from the University of Missouri have found that United States consumers are more willing to buy clothing made from sustainably grown US cotton than apparel produced using conventional practices in an unknown location.
When Hiroaki Matsunami, Ph.D., at Duke set out to study a chemical in male mouse urine called MTMT that attracts female mice, he didn't think he would stumble into a new field of study. But the research has led scientists at Duke University Medical Center and the University of Albany to the discovery that it's the copper in our bodies that makes mammals recoil from sulfur chemical smells.
A recent discovery by Van Andel Research Institute scientists enables the prediction of patient sensitivity to proposed drug therapies for glioblastoma - the most common and most aggressive malignant brain tumor in humans.
There are ways in which patients who leave the hospital against medical advice wind up paying for that decision. Being saddled with the full cost of their hospital stay, however, is not one of them.
